     Test that page_range works correctly when requesting pages beyond index 32.
-    
+
     This test verifies the fix for the bug where page_range would stop at page 32
     when the range started from page 30 or higher.
-    
+
     Bug scenario:
     - page_range=(30, 35) would only extract pages 30-32 instead of 30-35
     - Pages with page_no >= 32 (0-indexed) were not being processed
-    
+
     Root cause was a hardcoded batch_size=32 in the drain loop.
